To go with the above article, I thought I'd include
this one. It doesn't sound fully confirmed, but it
hasn't been refuted by anyone I've seen yet. Francis
crick was on LSD when he discovered DNA?

Excerpt:

The abrasive and unorthodox Crick and his
brilliant American co-researcher James Watson
famously celebrated their eureka moment in March
1953 by running from the now legendary Cavendish
Laboratory in Cambridge to the nearby Eagle pub,
where they announced over pints of bitter that they
had discovered the secret of life.Crick, who died
ten days ago [2004-07-28], aged 88, later told a
fellow scientist that he often used small doses of
LSD, then an experimental drug used in
psychotherapy, to boost his powers of thought. He
said it was LSD, not the Eagle's warm beer, that
helped him to unravel the structure of DNA, the
discovery that won him the Nobel Prize.
